Embodiment Construction

[0053] Now, embodiments of the present invention will be described with reference to the drawings.

[0054]FIG. 1 shows an example construction of an image processing apparatus according to an embodiment of the present invention.

[0055] The image processing apparatus shown in FIG. 1 includes a computer 11, and a digital camera (digital video camera) 12 that supplies images to the computer 11. The computer 11 is connected to the Internet 13.

[0056] A central processing unit (CPU) 31, a memory 32, a display controller 33, an input-device interface 34, a network interface 35, and an external-device interface 36 are connected to each other via a bus 37.

[0057] The CPU 31 runs an operating system (OS) stored in a hard disk drive (HDD) 41, and runs various programs (application programs) under the control of the operating system. For example, the CPU 31 stores (saves) in the HDD 41 image data of a plurality of images supplied from the digital camera 12 via the external-device interface 36. ...

Abstract

An image processing apparatus that performs image processing on a first image and a second image includes a dividing unit dividing the first image into a plurality of blocks; a first motion-vector calculator calculating first motion vectors representing movements from the blocks of the first image to corresponding regions of the second image; a second motion-vector calculator calculating second motion vectors representing movements of the blocks that occur when the blocks are transformed based on a first positional-relationship parameter representing positional relationship between the first image and the second image; a difference-vector calculator calculating difference vectors representing differences between the first motion vectors and the second motion vectors; and an extracting unit extracting blocks including a moving object or blocks including a non-moving object based on distribution density of end points of the difference vectors.

Description

CROSS REFERENCES TO RELATED APPLICATIONS [0001] The present invention contains subject matter related to Japanese Patent Application JP 2004-137975 filed in the Japanese Patent Office on May 7, 2004, the entire contents of which are incorporated herein by reference.
